When you say supports 1080i, do you mean that is what you want it to display? Or do you just want it to accept the signal but it can display it in whatever the projectors native resolution is? If you are looking for a projector to actually display 1080i for around $1000, I think you will have quite a wait. If you just want it to be able to handle the signal then there are some out there that can take a 1080i signal and display it at 720p or less.
